By convention, handlers with ordinary priority should begin with "m".

Method overview

Attributes

When the application is launched with the -help argument, this attribute is retrieved and displayed to the user (on stdout). The text should have embedded newlines which wrap at 76 columns, and should include a newline at the end. By convention, the right column which contains flag descriptions begins at the 24th character. Read only.

Methods

handle()

Processes a command line. If this handler finds arguments that it understands, it should perform the appropriate actions (such as opening a window), and remove the arguments from the command-line array.
